Abstract: A mounting device includes a mounting box, a tray, and a sliding mechanism. The mounting box includes a bottom plate. The sliding mechanism includes a handle and at least one driving member. The driving member is movably coupled to the handle. In a pull configuration of the sliding mechanism, when the handle is rotated toward the bottom plate, the driving member is driven to drive the tray to move along a first direction, and when the handle is rotated away from the bottom plate, the tray is not driven to move. In a push configuration of the sliding mechanism, when the handle is rotated toward the bottom plate, the tray is not driven to move, and when the handle is rotated away from the bottom plate, the driving member is driven to drive the tray to move toward a second direction opposite to the first direction.

Abstract: A cover plate for locking a chassis includes a first cover section provided on top of the chassis, a second cover section provided on top of the chassis and having a positioning pin, and a resilient lock defining a through hole corresponding to the positioning pin. When the resilient lock is in a first position, the positioning pin is latched in the through hole, one end of the first cover section abuts against one end of the second cover section, and the cover plate is locked. When the resilient lock is in a second position, the positioning pin is removed from the through hole, the first cover section is slid toward the second cover section, and the cover plate is unlocked.

Abstract: An apparatus for protecting cables outside a server casing is between a cable managing assembly and a sliding bracket. The cable managing assembly is slidable on the bracket to allow manual operations to the server (in the working position) or can be in a nonworking position. The protecting apparatus includes locking member, latching member, and latching portion. An end of the locking member is rotatably mounted to a casing, the other end defines a locking pin. The latching member on the sliding bracket has a latching slope corresponding to the locking pin. In the working position, the latching portion and locking member can be separated, the locking member is thus released, and the sliding bracket is free to move. In the nonworking position, the latching portion resists the locking member and prevents rotation of the locking member and movement of the sliding bracket.
